MT, I have fiends in New Mexico who all hunt elk with .257 Roberts, but they hunt in heavy juniper and rarely have shots out to 100 yards. I have 2 .257 Wby's and they are used for deer and javalena. The Unit we hunt elk here in Az the shots are 300-500 on average. I lean toward my larger caliber Wby's for that reason since I'm not a perfect shot. I read Roy killed an elephant once with his .257 Wby which sounds a bit extreme. Give your .257 a try and let us know how it performed. Good luck
